A drill pipe typically constitutes a large portion, usually around 95%, of what is known as the 'drill string'. Read on for more information on drill strings!
Drill pipes made out of steel are the most common. The specific steel alloy used is typically high-strength, low-alloy steel (HSLA). This type of steel is chosen for its ability to withstand the harsh conditions encountered during drilling, including high-stress levels, corrosion, and wear.
Aluminum is also occasionally chosen, due to its light-weight characteristic. Aluminum pipes are well-suited for situations where weight is a critical factor, such as remote drilling or when equipment weight limitations need to be considered.
In some cases, drill pipes may be coated with materials like nickel or other anti-corrosion coatings to provide additional protection against corrosion.
N-Class (New Pipe): These are the strongest and newest pipes available, typically in excellent or near-pristine condition.
P-Class (Premium Pipe): Premium pipes are a step down from N-Class. They have experienced some wear but are still highly functional.
C-Class (Used Pipe): C-Class pipes further subdivide into C-1, C-2, and C-3, depending on their condition. They range from well-worn pipes to those nearing the end of their serviceable life. The specific rating indicates the extent of wear and longevity, making C-Class pipes suitable for less demanding drilling tasks.

A regular drill pipe, or standard drill pipe, comes in various sizes and outer diameters. The most common outside diameter for regular drill pipes ranges from approximately 2 3/8 inches to 6 5/8 inches.
Drilling pipes are typically manufactured in standard lengths, with the most common options being 30 feet (9 meters) and 45 feet (14 meters). Longer lengths may be used for deeper drilling projects.
A heavy weight drill pipe (HWDP) is characterized by its thicker walls and significantly higher weight per foot (lb/ft) compared to regular drill pipes. These attributes make a heavy weight drill pipe exceptionally well-suited for demanding drilling applications.
HWDP is designed to address challenges like borehole control, wellbore stability, and high-pressure environments in deep drilling. Its added weight helps maintain drilling accuracy.
Vigor's drill pipes are produced according to API 5DP standard, we can provide you with API 5DP Grade: E,95(x),105(G),135(5) grades for production, if you are interested in Vigor drill pipes or other downhole drilling tools used in the oil and gas industry, please do not hesitate to contact us.
